12Gib AdjustmentAfter a period of time, movement of the tableover the ways will cause normal wear. To adjustthe gibs for this wear:1. The horizontal gib adjustment screw (A, Fig.13) is found to the right on the table face.The traverse gib adjustment screw (B, Fig.13) is found on the right side of the saddleunder the table.2. Turn each screw slightly clockwise to tighten.Turn the table hand wheels and check thetension.3. Re-adjust as required.Power Feed Operation (JMD-18PFN only)Make all power feed settingswith power to the machine turned off. Failureto comply may cause damage to the machine.1. Set the power feed speed range dial (C, Fig.14) to the desired rate.2. Set the depth stop to the desired setting bylowering the quill to the desired depth andholding in place. Turn the collar (D, Fig. 14)counter-clockwise until zero is indicated andthen tighten the lock handle (E, Fig. 14)3. Start the mill/drill and pull one of two handles(F, Fig. 14) away from the column to startthe power downfeed.4. Once the downfeed has reached the depthstop, the trip will release and the spindle willretract.5. To stop the feed before the cycle has endedor to disengage the fine feed (G, Fig. 14),press one of two handles toward the column.Adjusting the Spindle Return SpringThe spindle return comes pre-set from thefactory and should not need any adjustment.1. You do not want to remove the spring cap(H, Fig. 15).2. Loosen knob (I, Fig. 15) just enough torotate spring cap past the notch (J, Fig. 15).3. Rotate the spring cap clockwise to decreasespring tension. Rotate the spring capcounter-clockwise to increase spring tension.
